[0023] The applicant of this application has the following concurrently filed U.S. patent applications, the disclosures of each of which are incorporated herein by reference in their entirety: U.S. Patent Application No. 18 / 950,801 entitled “IMPROVED FILTER LIFE IN SURGICAL Smoke EVACUATION SYSTEMS”; U.S. Patent Application No. 18 / 950,899, entitled “AIR MANAGEMENT IN SURGICAL SMOKE EVACUATION SYSTEMS”; and U.S. Patent Application No. 18 / 951,268 entitled “INTELLIGENT INSUFFLATION AND SMOKE EVACUATION”.

[0024] This disclosure relates to energy devices, blowing systems for delivering blown gas to a patient, and extraction systems for removing smoke and / or other fluids and / or particles from a surgical site.

[0025] Smoke is typically generated during surgical procedures using an energy device that uses energy to affect (treat) tissue. In this energy device, energy is supplied by a generator. Energy devices include those with tissue-contact electrodes, such as electrosurgical devices with one or more radiofrequency (RF) electrodes, and those with vibrating surfaces, such as ultrasonic devices with an ultrasonic scalpel. For electrosurgical devices, the generator is configured to generate an oscillating current to power the electrodes. For ultrasonic devices, the generator is configured to generate ultrasonic vibrations to power the ultrasonic scalpel. The generator is further described herein, and a suction module is used to control the amount of smoke generated by the energy device during its use.

[0026] Figure 1This is a block diagram of a computer-implemented interactive surgical system 100 (hereinafter referred to as "surgical system 100") that can be used according to at least one aspect of this disclosure. Surgical system 100 includes one or more sub-surgical systems 102 and a cloud-based system (e.g., cloud 104), which may include a remote server 113 communicating with a storage device 105. Each sub-surgical system 102 includes at least one surgical hub 106 communicating with the cloud 104, which may include the remote server 113.

[0027] In one example, such as Figure 1 As illustrated, subsurgical system 102 includes visualization system 108, robotic system 110, and handheld intelligent surgical instruments 112, which are configured to communicate with each other and / or with hub 106. In some aspects, each subsurgical system 102 may include M hubs 106, N visualization systems 108, O robotic systems 110, and P handheld intelligent surgical instruments 112, where M, N, O, and P are integers greater than or equal to one. Surgical system 100 is described in more detail in U.S. Patent No. 11,666,368, entitled “METHOD FOR CONSTRUCTING AND USING A MODULARSURGICAL ENERGY SYSTEM WITH MULTIPLE DEVICES,” published June 6, 2023, the entire contents of which are incorporated herein by reference.

[0028] Now for reference Figure 2 Example surgical hub 106 ( Figure 1 The system can be embodied as a modular surgical system 200, which may include various different modules 201 capable of being connected together in a stacked configuration. In one aspect, the modules 201 may be physically and communicatively coupled together when stacked or otherwise connected together to form a single component. Furthermore, the modules 201 may be interchangeably connected together in different combinations or arrangements. In one aspect, each module in the module 201 may include a consistent or universal array of connectors disposed along its upper and lower surfaces, thereby allowing any module 201 to be connected to another module 201 in any arrangement (the difference being that, in some aspects, a particular module type (such as head module 202) may be configured to be used as, for example, the topmost module within a stack). In another aspect, the modular surgical system 200 may include a housing configured to receive and retain the modules 201. The modular surgical system 200 may also include various different parts or accessories that can also be connected to or otherwise associated with the modules 201.

[0029] The modular surgical system 200 can be assembled from a variety of different modules 201, some examples of which are shown in... Figure 2 As illustrated below. Each module in the different types of modules 201 can provide different functionalities, thereby allowing the modular surgical system 200 to be assembled into different configurations to customize the functionality and capabilities of the modular surgical system 200 (e.g., by customizing the modules 201 included in each modular surgical system 200). Modules 201 of the modular surgical system 200 may include, for example, a head module 202 (which may include a display 206), an energy module 204, a suction module 208, an inhalation module 210, and a visualization module 212.

[0030] In one aspect, the head module 202 is configured to function as a top or uppermost module within a modular surgical system stack, and therefore may be connector-free along its top surface. In another aspect, the head module 202 can be configured to be positioned at the bottom or lowermost module (i.e., the "footer" module) within the modular surgical system stack, and therefore may be connector-free along its bottom surface. In yet another aspect, the head module 202 can be configured to be positioned at an intermediate location within the modular surgical system stack, and therefore may include connectors along both its bottom and top surfaces. The head module 202 can be configured to be accessible via physical controls 411 on the head module ( Figure 4A ) and / or a graphical user interface (GUI) 408 presented on display 206. Figure 4A The head module 202 is configured to control system-level settings for each module 201 and the components connected to each module. Such settings may include activation of the modular surgical system 200, alert volume, foot switch settings, settings icons, the appearance or configuration of the user interface, surgeon profiles logged into the modular surgical system 200, and / or the type of surgical procedure being performed. The head module 202 may also be configured to provide communication, processing, and / or power to the modules 201 connected to it.

[0031] Energy module 204 (optionally referred to as generator module) can be configured to generate one or more energy modes for driving electrosurgical instruments and / or ultrasound surgical instruments connected thereto. For example, see reference... Figure 3The generator 204 is configured to drive multiple surgical instruments 300, 330, and 360. The first surgical instrument is an ultrasonic surgical instrument 300 and includes a handpiece 302 (HP), an ultrasonic transducer 304, a shaft 306, and an end effector 308. The end effector 308 includes a gripping arm 312 and an ultrasonic scalpel 310 acoustically coupled to the ultrasonic transducer 304. The handpiece 302 includes a trigger 314 for operating the gripping arm 312 and a combination of toggle buttons 316a, 316b, and 316c for powering and driving the ultrasonic scalpel 310 or other functions. The toggle buttons 316a to 316c can be configured to power the ultrasonic transducer 304 using the generator 204.

[0032] Generator 204 is also configured to drive a second surgical instrument 330, which is an RF electrosurgical instrument and includes a handpiece 332 (HP), a shaft 334, and an end effector 336. The end effector 336 includes electrodes in gripping arms 338a, 338b and returns through an electrically conductive portion of the shaft 334. These electrodes are coupled to and powered by a bipolar energy source within generator 204. The handpiece 332 includes a trigger 340 capable of manual actuation to operate the gripping arms 338a, 338b and an energy button 342 for actuating an energy switch to power the electrodes in the end effector 336.

[0033] Generator 204 is also configured to drive a third surgical instrument 360, which is a multi-functional surgical instrument 360 and includes a handpiece 362 (HP), a shaft 364, and an end effector 366. The end effector 366 includes an ultrasonic scalpel 368 and a clamping arm 370. The ultrasonic scalpel 368 is acoustically coupled to an ultrasonic transducer 372. The handpiece 362 includes a trigger 374 for operating the clamping arm 370 and a combination of toggle buttons 376a, 376b, and 376c for powering and driving the ultrasonic scalpel 368 or other functions. The toggle buttons 376a to 376c can be configured to power the ultrasonic transducer 372 using generator 204 and the ultrasonic scalpel 368 using a bipolar energy source also included in generator 204. Further aspects of surgical instruments are described in U.S. Patent No. 10,624,691, entitled “TECHNIQUES FOR OPERATING GENERATOR FOR DIGITALLY GENERATING ELECTRICAL SIGNAL WAVEFORMS AND SURGICALINSTRUMENTS”, published on April 21, 2020, the entire contents of which are incorporated herein by reference.

[0034] Pumping module 208 ( Figure 2The device can be configured to expel fumes, fluids, and / or particles generated by the application of therapeutic energy to tissue by one or more surgical instruments selected from surgical instruments 300, 330, and 360. Example expulsion modules are described in more detail elsewhere herein and in U.S. Patent No. 11,602,393, entitled “SURGICAL EVACUATION SENSING ANDGENERATOR CONTROL,” published March 14, 2023, which is incorporated herein by reference in its entirety. Blow-in module 210 ( Figure 2 It can be configured to blow air or gas into a patient's body cavity to inflate it for diagnostic or surgical purposes, thereby providing better visibility and access during surgery.

[0035] Visualization Module 212 ( Figure 2 This can be configured to interact with visualization devices (i.e., observation devices), and thus provide enhanced visualization capabilities. Example visualization modules and systems are described in more detail in U.S. Patent No. 11,284,963, entitled “METHOD OF USING IMAGING DEVICES IN SURGERY,” published March 29, 2022, which is incorporated herein by reference in its entirety.

[0036] Refer again Figure 2 The modular surgical system 200 may also include various accessories 229 that can be connected to the module 201 for controlling its functions, or are otherwise configured to work in conjunction with the modular surgical system 200. Accessories 229 may include, for example, a single-pedal foot switch 232, a double-pedal foot switch 234, and a trolley 230 for supporting the modular surgical system 200 thereon. Foot switches 232 and 234 may be configured to control the activation or function of, for example, a specific energy mode output by the energy module 204.

[0037] By utilizing modular components, the depicted modular surgical system 200 provides a surgical platform that is optimized for technological availability and can be customized to the needs of facilities and / or surgeons. Furthermore, the modular surgical system 200 supports combined devices (e.g., dual-electrosurgical and ultrasound energy generators) and software-driven algorithms for customized tissue effects. Moreover, the surgical system architecture reduces capital footprint by combining multiple technologies essential for surgical procedures into a single system.

[0038] Various modular components that can be used in conjunction with the modular surgical system 200 may include a monopolar energy generator, a bipolar energy generator, a dual-electric surgical / ultrasound energy generator, a display screen, and various other modules and / or components described elsewhere herein.

[0039] Now for reference Figure 4A In some aspects, head module 202 may include display screen 206, which presents GUI 408 for relaying information about module 201 connected to head module 202. Figure 2 Information. In some aspects, the GUI 408 of the display screen 206 can provide a unified control point for all modules 201 constituting a specific configuration of the modular surgical system 200. In another aspect, the head module 202 may not include the display screen 206, or the display screen 206 may be detachably attached (removably attached) to the housing 410 of the head module 202. In such aspects, the head module 202 may be communicatively coupled to an external system configured to display information generated by the modules 201 of the modular surgical system 200. For example, in robotic surgical applications, the modular surgical system 200 may be communicatively coupled to a robotic cart or robotic console configured to display information generated by the modular surgical system 200 to the operator of the robotic surgical system. As another example, the modular surgical system 200 may be communicatively coupled to a mobile display that can be carried or attached to a surgical worker for viewing. In terms of utilizing a user interface that is separate from or otherwise different from the modular surgical system 200, the user interface may be able to wirelessly connect to the modular surgical system 200 as a whole or one or more modules 201 thereon, so that the user interface can display information from the connected module 200 thereon.

[0040] Still referencing Figure 4A The energy module 204 may include a port assembly 412 that includes (provides) a plurality of different ports configured to deliver different energy modes to corresponding surgical instruments that can be connected to these ports (e.g., for example, Figure 3 Surgical instruments 300, 330, 360). In Figure 4A As illustrated in the specific embodiment, port assembly 412 includes a bipolar port 414, a first unipolar port 416a, a second unipolar port 416b, a neutral electrode port 418 (to which a unipolar return pad can be connected), and a combined energy port 420. However, this specific combination of ports is provided only for illustrative purposes, and alternative combinations of ports and / or energy modes may be possible for port assembly 412.

[0041] As noted above, the modular surgical system 200 can be assembled into different configurations. Furthermore, different configurations of the modular surgical system 200 can also be used for different types of surgical procedures and / or different tasks. For example, Figure 4A and Figure 4B A first exemplary configuration of a modular surgical system 200 is illustrated, which includes a head module 202 (including a display screen 206) and an energy module 204 connected together. This configuration can be used for, for example, laparoscopic and open surgical procedures. Figure 4B As shown, the modular surgical system 200 can be positioned on a trolley 230, thereby enabling the modular surgical system 200 to be easily moved (rolled) around the operating room, for example.

[0042] Figure 5 A second exemplary configuration of a modular surgical system 200 is illustrated, which includes a head module 202 (including a display screen 206), a first energy module 204a, a second energy module 204b, and a drainage module 208 connected together and positioned on a cart 230. In this configuration, the drainage module 208 can drain smoke, fluid, and / or particles generated by surgical instruments powered by the energy modules 204a and 204b.

[0043] Figure 6 This is a block diagram of an example modular surgical system 600 according to at least one aspect of the present disclosure. As illustrated, the modular surgical system 600 includes a head module 202 (including a display screen 206), an energy module 204 stacked below the head module 202 and connected to the head module, an exhaust module 208 stacked below the energy module 204 and connected to the energy module, and an inhalation module 210 stacked below the exhaust module 208 and connected to the exhaust module.

[0044] Head module 202 is configured to monitor, control, power, and provide feedback on the operation of modules within the modular surgical system 600, such as energy module 204, suction module 208, and inhalation module 210. As illustrated, head module 202 includes a controller 620 comprising a processor 622 and a memory 624 storing computer-readable instructions executable by the processor 622 to implement the functions and operations of head module 602. Examples of memory 624 include, but are not limited to, random access memory (RAM), read-only memory (ROM), computer chips, optical discs (e.g., CDs, DVDs, etc.), and magnetic disks (e.g., hard disk drives (HDDs), floppy disks, ZIP drives). ®Disks, magnetic tapes, and solid-state storage devices (e.g., memory cards, "flash" media, etc.). As used herein, the term "computer-readable medium" means any device or system used to store information (e.g., data and instructions) and provide it to processor 622. Examples of computer-readable media include, but are not limited to, optical discs, magnetic disks, magnetic tapes, solid-state media, and servers for streaming media on a network.

[0045] Based on instructions stored in memory 624, processor 622 can be configured to control power and data transmission between head module 202, energy module 204, exhaust module 208, and blow-in module 210 via power interface 608 and data interface 610. For example, head module 202 can transmit various commands to energy module 204, exhaust module 208 (via energy module 204), and blow-in module 210 (via energy module 204 and exhaust module 208) via data interface 610. Such commands can be based on user input received at display 206 or input received by controller 620 from various sensors communicatively coupled to modular surgical system 600, as discussed elsewhere herein.

[0046] As another example, power can be transferred from head module 202 to energy module 204, exhaust module 208 (via energy module 204), and blow-in module 210 (via energy module 204 and exhaust module 208) via power interface 608. For example, head module 202 can receive power from an external power source 660 (referred to herein as "AC mains") such as a wall socket. Head module 202 may include an AC / DC converter 662 that receives AC power from AC mains 660 and converts the AC power to DC power. Controller 202 can then distribute the DC power to energy module 204, exhaust module 208, and blow-in module 210 via power interface 608. Controller 620 may also include a timer 626 for measuring elapsed time. Head module 202 may include a sensor 628, such as a current sensor and / or a power sensor, which is operatively communicateable with controller 620 for measuring current and power along power interface 608.

[0047] like Figure 6 As shown, the energy module 204 may include a controller 680, which includes a processor 682 and a memory 684 storing computer-readable instructions executable by the processor 682 to implement the functions and operations of the energy module 204. The processor 682 and memory 684 may be similar to processor 622 and memory 624, respectively. The controller 680 may receive power from an AC / DC converter 662 along a power interface 608 and may operatively communicate with a controller 620 via a data interface 610.

[0048] Energy module 204 may also include energy generator 670. Energy generator 670 may receive power from AC / DC converter 662 along power interface 608 and may operatively communicate with controller 680, such as via a wired or wireless connection. For example, energy generator 670 may be operable to provide therapeutic energy to one or more surgical instruments (such as surgical instruments 300, 330, 360) via port assembly 412 (such as via bipolar port 414 (FIG. 4), a first unipolar port 416a or a second unipolar port 416b (FIG. 4) or a combined energy port 420 (FIG. 4)). For example, energy generator 670 may be powered using DC power supplied to it from AC / DC converter 662 along power interface 608. Controller 680 may then receive input, such as from controller 620. Based on this input, controller 680 may control energy generator 670 to provide therapeutic energy to one or more surgical instruments coupled to energy module 204 at port assembly 412. The energy generator 670 may include a sensor 672, such as a current sensor and / or a power sensor, which is operatively communicatively connected to the controller 680 for measuring the current and / or power supplied by the energy generator 670. The sensor 672 may also include an impedance sensor for measuring the impedance of tissue grasped by a surgical instrument in a surgical apparatus.

[0049] like Figure 6 As shown, display screen 206 includes a touchscreen 630 coupled to touch controller 632. Touch controller 632 is coupled to controller 620 to read input from touchscreen 630, such as user input. Controller 620 drives LCD display 640 via display / port video output signal 642. Controller 620 is also coupled to audio amplifier 652 to drive one or more speakers 650.

[0050] Surgical air infusion Minimally invasive surgery often requires the creation of a gas-filled cavity to provide the surgeon with sufficient visibility and space to manipulate instruments, such as... Figure 3 Energy delivery devices 300, 330, and 360. The gas filling chamber can utilize a blow-in module (such as blow-in module 210). Figure 2 To generate.

[0051] Figure 7 It is based on at least one aspect of this disclosure Figure 2A schematic diagram of the internal components of the blow-in module 210. The blow-in module 210 may include a blow-in housing 700, which contains a fan or pump 702, a humidifier 703, a heat storage tank 704, a heater 705, and an exhaust mechanism 706, all positioned within the blow-in housing. In some embodiments, the heater 705 may be operable to generate heat, and the heat storage tank 704 is configured to receive and store the heat generated by the heater 705. The stored heat may be used to passively heat the gas moving through the blow-in module 210, as will be described in more detail below. Alternatively, in other embodiments, the heat storage tank 704 may be omitted, and the heater 705 may be operable to actively heat the gas moving through the blow-in module 210. The humidifier 703 may be operable to humidify the gas moving through the blow-in module 210, as will be described in more detail below. A motor 718 is provided to drive the pump 702. When the blow-in module 210 is stacked with the head module 202, it is similar to... Figure 6 As shown in the arrangement, the motor 718, humidifier 703, and heater 705 can receive power from the AC / DC converter 662 via the power interface 608.

[0052] The blow-in module 210 defines a flow path 708 (partially shown in dashed lines) that extends through the blow-in housing 700 and has an inlet port 710 and an outlet port 712. A pump 702, a humidifier 703, a heat reservoir 704, and an exhaust mechanism 706 are arranged sequentially in series within the flow path 708, passing through the blow-in housing 700 between the inlet port 710 and the outlet port 712. The outlet port 712 can be fluidly coupled to a cannula that is in fluid communication with a patient's internal lumen (e.g., the patient's peritoneal cavity).

[0053] Inlet port 710 can be fluidly connected to gas source 720 via conduit 722 (pipe). As an example, gas source 720 may contain gases such as carbon dioxide (CO2), nitrous oxide (N2O), helium, oxygen, air, xenon, argon, or nitrogen (N2).

[0054] Pump 702 is configured to generate a pressure difference in flow path 708 through mechanical action. This pressure difference draws gas 714 from gas source 720 through conduit 722 to inlet port 710 and along flow path 708. After moving through humidifier 703 and heat storage tank 704, gas 714 can be considered “heated / humidified” gas 716 (referred to herein as “blow-in” gas 716), which can continue through flow path 708 and exhaust mechanism 706, ultimately exiting (emitting) through outlet port 712. Exhaust mechanism 706 can control the rate, direction, and / or other properties of the blow-in gas 716 exiting blow-in module 210 at outlet port 712.

[0055] The flow path 708 through the blow-in module 210 may be formed by a pipe or other conduit that substantially contains the fluid moving through the flow path 708 and / or isolates the fluid moving through the flow path from the fluid outside the flow path 708 (the surrounding environment).

[0056] Surgical smoke extraction As presented in this article, energy devices (such as...) Figure 3 Energy delivery devices 300, 330, 360 deliver mechanical (e.g., ultrasound) and / or electrical (e.g., RF) energy to target tissue for therapeutic purposes (e.g., cutting tissue, cauterizing blood vessels, and / or coagulating tissue within and / or near the target tissue). Cutting, cauterizing, and / or coagulating tissue can result in the release of fluids and / or particles into the air. Such fluids and / or particles released during surgical procedures can constitute a smoke, which may include, for example, carbon particles and / or other particles suspended in the air. In other words, the fluid may include smoke and / or other fluid substances.

[0057] Approximately 90% of endoscopic and open surgical procedures generate some level of smoke. This smoke can be unpleasant to clinicians, assistants, and / or patients, may hinder the clinician's view of the surgical site, and in some cases may be unhealthy to inhale. For example, smoke generated during electrosurgery can contain toxic chemicals including acrolein, acetonitrile, acrylonitrile, acetylene, alkylbenzene, benzene, butadiene, butene, carbon monoxide, cresol, ethane, ethylene, formaldehyde, free radicals, hydrogen cyanide, isobutylene, methane, phenol, polycyclic aromatic hydrocarbons, propene, propylene, pyridine, pyrrole, styrene, toluene, and xylene, as well as dead and living cell material (including blood fragments) and viruses. Some substances identified in surgical smoke have been classified as containing known carcinogens. It is estimated that one gram of tissue cauterized during electrosurgery is equivalent to the toxins and carcinogens of six unfiltered cigarettes. Additionally, exposure to smoke released during electrosurgery has been reported to cause eye and lung irritation for healthcare workers.

[0058] In addition to the toxicity and odor associated with the materials in surgical smoke, the size of the particles in surgical smoke can be harmful to the respiratory systems of clinicians, assistants, and / or patients. In some cases, the particles can be very small, and in some cases, repeated inhalation of very small particles can lead to acute and chronic respiratory illnesses.

[0059] Many electrosurgical systems employ surgical evacuation systems that inhale and capture fumes generated during surgery and direct the captured fumes through filters and exhaust ports away from clinicians and / or patients. For example, evacuation systems (such as evacuation module 208) Figure 2 A system can be configured to remove smoke generated during electrosurgery. Such a system can be called a "smoke extraction system," but it can also be configured to remove more than just smoke from the surgical site.

[0060] Throughout this disclosure, the “smoke” expelled by the extraction system is not limited to mere smoke. Rather, the smoke extraction system disclosed herein can be used to extract a variety of fluids, including liquids, gases, vapors, fumes, steam, or combinations thereof. The fluid may be of biological origin and / or may be introduced to the surgical site from an external source during surgery. Fluids may include, for example, water, saline, lymph, blood, exudate, and / or purulent discharge. Furthermore, the fluid may include particles or other substances (e.g., porous materials or fragments) expelled by the extraction system. For example, such particles may be suspended in the fluid.

[0061] Figure 8 It is based on at least one aspect of this disclosure Figure 2A schematic diagram of the internal components of the exhaust module 208. The exhaust module 208 includes an exhaust housing 801, within which a fan or pump 804 and a filter 800 are positioned. Smoke drawn into the exhaust housing 801 travels to the filter 800, and as the smoke moves through (crosses) the filter 800, harmful toxins and pungent odors are filtered out. The filtered air 814 can then exit the exhaust module 208 as exhaust gas.

[0062] The suction module 208 defines a flow path 806 (shown in dashed lines) that extends through the suction housing 801 and has an inlet port 808 and an outlet port 810. A filter 800, a pump 804, and a venting mechanism 802 are arranged sequentially in series within the flow path 806, passing through the suction housing 801 between the inlet port 808 and the outlet port 810. The inlet port 808 can be fluidly coupled to a suction catheter 702, which may include a distal catheter opening capable of being positioned at a surgical site.

[0063] Pump 804 is configured to generate a pressure differential in flow path 806 by mechanical action. This pressure differential is configured to draw smoke 812 from the surgical site into inlet port 808 and along flow path 806. After passing through filter 800, smoke 812 can be considered “filtered” smoke or air 814 (referred to herein as “filtered air 814”), which can continue through flow path 806 and eventually be discharged (emitted) through outlet port 810.

[0064] As illustrated, flow path 806 may include a first zone 816 and a second zone 818. The first zone 816 is located upstream of pump 804; the second zone 818 is located downstream of pump 804. Pump 804 is configured to generate a vacuum and otherwise pressurize the fluid in flow path 806 to drive the fluid from the first zone 816 to the second zone 818 via pump 804. Motor 820 drives pump 804. When pumping module 208 is stacked with head module 202, it is similar to... Figure 6 As shown in the arrangement, the motor 820 can receive power from the AC / DC converter 662 via the power interface 608. The exhaust mechanism 802 is a mechanism that can control the speed, direction, and / or other properties of the filtered air 814 leaving the exhaust module 208 at the outlet port 810.

[0065] The flow path 806 through the exhaust module 208 may be constructed of a pipe or other conduit that substantially contains the fluid moving through the flow path 806 and / or isolates the fluid moving through the flow path from fluids outside the flow path 806 (the surrounding environment). For example, a first region 816 of the flow path 806 may include a pipe through which the flow path 806 extends between the filter 800 and the pump 804. A second region 818 of the flow path 806 may also include a pipe (conduit) through which the flow path 806 extends between the pump 804 and the exhaust mechanism 802. The flow path 806 also extends through the filter 800, the pump 804, and the exhaust mechanism 802, such that the flow path 806 extends continuously from the inlet port 808 to the outlet port 810.

[0066] In operation, smoke 812 can flow into filter 800 after passing through inlet port 808, and can be pumped by pump 804 through flow path 806, so that smoke 812 is drawn into filter 800. Then, filtered air 814 discharged from filter 800 can be pumped through exhaust mechanism 802 and discharged from outlet port 810 of exhaust module 208. The filtered air 814 leaving exhaust module 208 at outlet port 810 is exhaust gas and can be composed of gas that has passed through exhaust module 208. Additional information about exhaust module 208 is described in U.S. Patent No. 11,602,393, entitled “SURGICAL EVACUATION SENSING AND GENERATOR CONTROL”, published March 14, 2023, which is incorporated herein by reference in its entirety.

[0067] According to embodiments of this disclosure, the exhaust module 208 may further include a plurality of sensors 820a, 820b, 820c, 820d positioned along the flow path 806 for measuring one or more parameters associated with the smoke 812 and / or filtered air 814 flowing along the flow path 806. When the exhaust module 208 is in a stacked configuration with the head module 202, such as when in a stacked configuration... Figure 6 The configuration shown, for example, allows sensors 820a to 820d to operatively communicate with controller 620, such as via data interface 610. Figure 6 And it can be accessed via power interface 608 ( Figure 6 The controller 620 receives power from the head module 202. The controller 620 can receive measurement results from sensors 820a to 820d and control various operations of the modular surgical system based on these measurement results. For example, in some embodiments, the controller 620 can control the speed of the motor 820 based on the received measurement results.

[0068] One or more of sensors 820a to 820d may include flow sensors for measuring the flow rate of smoke 812 / filtered air 814 along flow path 806, such as, for example, the flow rate entering inlet port 808 (sensor 820a), the flow rate through first zone 816 (sensor 820b), the flow rate through second zone 818 (sensor 820c), and / or the flow rate exiting outlet port 810 (sensor 820d). Alternatively or as a supplement thereto, one or more of sensors 820a to 820d may include pressure sensors for measuring the pressure of smoke 812 / filtered air 814 along flow path 806, such as, for example, at inlet port 808 (sensor 820a), first zone 816 (sensor 820b), second zone 818 (sensor 820c), and / or at outlet port 810 (sensor 820d). In some implementations, sensors 820a to 820d can be used by controller 620 to measure pressure differences along flow path 806, such as pressure differences across filter 800, using first sensor 820a and second sensor 820b. Pumping module 208 may include a combination of both flow sensors and pressure sensors.

[0069] Lookup table for the amount of smoke produced by different devices Operating room (OR) staff (such as nurses) often have to manually adjust multiple settings of insulators and aspirators, such as run time, pressure, or flow rate, during surgical procedures as devices are changed and / or different surgical steps are performed. Systems and methods for preemptively and automatically adjusting settings can provide more efficient surgery with less technical support.

[0070] Refer again Figure 6 and Figure 8 The controller 620 can receive instructions to connect surgical instruments (e.g., surgical instruments) to the energy module 204. Figure 3 The controller 620 inputs the type of surgical instrument (one of the surgical instruments 300, 330, and 360) and the set power level for the associated surgical instrument. The controller 620 may include a lookup table in memory 624 that associates the type of surgical instrument and its power level with the motor speed of the suction motor 820. Therefore, the controller 620 can set the motor speed of the suction motor 820 according to the determined type and power level of the surgical instrument.

[0071] Figure 9 It is a control based on at least one aspect of this disclosure Figure 6 A schematic flowchart of an example method 900 for a modular surgical system 600. Method 900 can be embodied in a controller 620 (… Figure 6 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 ) to execute. Alternatively, the algorithm can be stored in the controller 680 ( Figure 6 ) memory 684 ( Figure 6 In, and can be controlled by the processor 682 of the controller 680. Figure 6 )implement.

[0072] refer to Figure 6 and Figure 9 Method 900 may include receiving a first input indicating the type of surgical instrument, as at step 902. For example, in some embodiments, a user may provide input to controller 620 via touchscreen 630 to inform controller 620 of the type of surgical instrument connected to or to be connected to power module 204. In other embodiments, a user may connect a surgical instrument to power module 204, and controller 620 may receive input based on this connection. For example, controller 620 may identify an instrument as a bipolar surgical instrument based on its connection to bipolar port 414 (FIG. 4), as a unipolar surgical instrument based on its connection to either a first unipolar port 416a or a second unipolar port 416b (FIG. 4), or as a combination instrument based on its connection to combination port 420 (FIG. 4).

[0073] Method 900 may further include receiving a second input indicating the power level of the surgical instrument, as at step 904. For example, based on the type of surgical instrument identified by controller 620, controller 620 may display an interactive widget on display 206, which a user can interact with to set and adjust the power level of the surgical instrument. An example widget is described in U.S. Patent No. 11,666,368, issued June 6, 2023, entitled “METHOD FOR CONSTRUCTING AND USING AMODULAR SURGICAL ENERGY SYSTEM WITH MULTIPLE DEVICES,” the contents of which are incorporated herein by reference in their entirety.

[0074] Method 900 may further include setting a first motor speed of the suction motor based on a first input and a second input, as at step 906. For example, the memory 624 of the controller 620 may include a lookup table that associates the type of surgical instrument and its set power level with the suction motor 820 ( Figure 8The controller 620 can retrieve a first motor speed of the suction motor 820 from memory 624 based on receiving a first input and a second input. The controller 620 can then set the motor speed of the suction motor 820 to the first motor speed. The selected motor speed may be sufficient to suction the amount of smoke expected to be generated by this type of surgical instrument at the set power level. The controller 620 can power the suction motor 820 at the first motor speed via power interface 608.

[0075] Method 900 may optionally include receiving a third input instructing adjustment of the power level, as at step 908, and adjusting the first motor speed to a second motor speed based on the third input, as at step 910. For example, after the controller 620 has set the first motor speed (step 906), the user may wish to increase or decrease the power level of the surgical instrument (the first power level) to a second power level. As described above, the user can provide input to the controller 620 via the touchscreen 630, thereby notifying the controller 620 that the power level of the surgical instrument needs adjustment. The controller 620 can adjust the first power level of the surgical instrument to the second power level based on the user input, while also retrieving from memory 624 the pumping motor 820 for that type of surgical instrument at the second power level. Figure 8 The second motor speed is selected. The chosen second motor speed may be sufficient to pump out the expected amount of smoke generated by this type of surgical instrument at the set second power level. The controller 620 can be connected via power interface 608. Figure 6 The second motor speed powers the pumping motor 820.

[0076] Therefore, the modular surgical system 600 can automatically set the suction motor 820 according to the type of surgical instrument and its associated power level. Figure 8 The motor speed allows the system to make changes proactively rather than passively.

[0077] Interfaces and software logic for creating intelligent interactive systems Refer again Figure 6 The controller 620 can use patient information (such as the patient's height and weight) to set one or more parameters of surgical modules (such as the suction module 208 or the blow-in module 210) used in the modular surgical system 600. The memory 624 of the controller 620 may include a lookup table that links patient information with the suction motor 820 (…). Figure 8 ) and / or blow-in motor 718 ( Figure 7The system associates the pre-selected motor speed with the controller 620. The user can provide patient information to the controller 620 via the touchscreen 630, and the controller 620 can retrieve the pre-selected motor speed from the memory 624 based on the provided patient information.

[0078] Users may wish to adjust a pre-selected motor speed retrieved from a lookup table. For example, controller 620 may display the retrieved pre-selected motor speed on display 206 as an interactive widget showing the pre-selected motor speed to the user. The user can interact with the interactive widget to adjust the motor speed (such as increasing or decreasing the motor speed) to the user-adjusted speed. Controller 620 may include a learning database, such as an artificial intelligence (AI) platform, that detects adjustments from the pre-selected motor speed to the user-adjusted motor speed. Based on user modifications to the settings, the learning database can self-update the lookup table to provide desired settings for a specific patient range. New setting information can be stored as new preferred settings in memory 624, resulting in a continuously adjusting / learning dataset. Therefore, the modular surgical system 600 can be referred to as an intelligent interactive system.

[0079] Controller 620 can control motors 718 and 820 (respectively...) Figure 7 and Figure 8 The controller 620 can be set to a pre-selected motor speed or a user-adjusted motor speed, and can power motors 718 and 820 via power interface 608. The controller 620 can also power motors 718 and 820 based on user input (such as input to touchscreen 630), surgical instruments (such as surgical instruments 300, 330, 360 connected to power module 204), or other inputs. Figure 3 One or more components of a modular surgical system 600 (a surgical instrument) are energized, or a combination thereof, to selectively power motors 718 and 820. For example, a user can power a device connected to a visualization module 212 ( Figure 2 The controller 620 can detect that the endoscope is powered, for example via a signal along the data interface 610, and automatically power one or both of the suction module 208 and the blow-in module 210 based on the detection.

[0080] Venturi system for smoke extraction Continue to refer to Figure 6 Due to the varying number of components in the modular surgical system 600 that draw power from it, it is desirable to optimize power consumption from the AC mains 660. The suction module 208 and the blow-in module 210 typically require significant power to drive the suction pump 804, respectively. Figure 8 ) and blow-in pump 702 ( Figure 7For example, using the exhaust module 208, there are different power requirements from the AC mains 660 depending on the operating environment. Laparoscopic surgery typically requires a first (lower) smoke extraction volume from the exhaust module 208, while open surgery typically requires a second (larger) smoke extraction volume greater than the first. These air intake and exhaust requirements can be met using a Venturi pump, which requires compressed air instead of electrical power.

[0081] Figure 10 This is a schematic diagram of the internal components of an example extraction module 1000 according to at least one aspect of this disclosure. The extraction module 1000 may be similar in some respects to... Figure 8 The pumping module 208 can be referenced for optimal understanding, where similar numbers will correspond to similar parts that will not be described in detail again.

[0082] The pumping module 1000 may include a venturi pump 1002 to replace pump 804. Figure 8 ) and motor 820 ( Figure 8 The exhaust module 1000 may define a T-shaped flow path 1004 (shown in dashed lines) that extends through the exhaust housing 801 and has a first inlet port 1006, a second inlet port 1008, and an outlet port 810. As an example, the first inlet port 1006 may be fluidly coupled to a gas source 1010, in which a gas 1012, such as compressed air or carbon dioxide, is stored. The gas source 1010 may be filled with gas from the blow-in pump 702 (…). Figure 7 The second inlet port 1008 may be fluidly connected to a suction catheter, which may include a distal catheter opening capable of being positioned at a surgical site.

[0083] In operation, gas 1012 can be supplied from gas source 1010 to pumping module 1000 via first inlet port 1006. For example, gas source 1010 can be connected to first inlet port 1006 via conduit 1013, which includes an electric valve 1015 configured to control the flow rate of gas 1012 from gas source 1010 to first inlet port 1006. Electric valve 1015 can include any suitable valve (ball, glove, gate, etc.) and a motor capable of operatively communicating with controller 620 to receive command signals from it. The command signal may include switching the electric valve 1015 between an open state, a closed state, and one or more intermediate states between the open and closed states. In the open state, the electric valve 1015 allows gas 1012 to flow to the first inlet port 1006. In the closed state, the electric valve 1015 prevents gas 1012 from flowing to the first inlet port 1006. In the one or more intermediate states, the electric valve 1015 allows partial flow of gas 1012 to the first inlet port 1006. For example, the electric valve 1015 may receive power from AC mains 660 or an AC / DC converter 662. In an alternative embodiment, a solenoid valve may be used instead of the electric valve 1015.

[0084] Gas 1012 can travel from the first inlet port 1006 through the flow path 1004 and reach the first inlet 1002a of the Venturi pump 1002. A constriction section (typically hourglass-shaped or a converging conduit) within the Venturi pump 1002 alters the flow characteristics of the gas 1012 traveling through it. As the velocity of the gas 1012 entering the first inlet 1002a of the Venturi pump 1002 increases, the pressure decreases. This negative pressure drop draws smoke 812 through the second inlet port 1008, along the flow path 1004, through the filter 800 (thus generating filtered air 814), and to the second inlet 1002b of the Venturi pump 1002. The filtered air 814 can be drawn into the flow path 1004 to mix with the gas 1012 in the venturi pump 1002, and the combined filtered air / gas 1014 can be discharged from the outlet 1002c of the venturi pump 1002 along the flow path 1004 to the exhaust mechanism 802, and then discharged from the outlet port 810.

[0085] Therefore, the aforementioned suction module 1000 can utilize compressed gas instead of electricity from AC mains 660 to extract smoke mist 812 from the surgical site, thereby reducing the power demand from AC mains 660. Other embodiments are envisioned, in which a venturi pump 1002 replaces pump 702. Figure 7 ) and Motor 718 ( Figure 7 ) for blow-in module 210 ( Figure 7In addition, the blow-in module 210 includes a similar arrangement of elements to the exhaust module 1000 (T-shaped flow path, gas source 1010, electric valve 1015, etc.).

[0086] Smoke exhaust UV Filter sterilization Refer again Figure 8 And, as described elsewhere herein, the exhaust motor 820 can be powered to drive the pump 804, thereby drawing the smoke 812 through the inlet port 808 and to the filter 800. Biomaterial from the smoke 812 can be captured by the filter 800. This biomaterial can support the growth of bacteria and other harmful organisms that may pose a potential health hazard to healthcare workers and patients. Therefore, it may be desirable to kill and / or inhibit the growth of bacteria and other harmful organisms on the filter 800 or other surfaces within the exhaust module 208.

[0087] Figure 11 This is a schematic diagram of the internal components of an example extraction module 1100 according to at least one aspect of this disclosure. The extraction module 1100 may be similar in some respects to... Figure 8 The pumping module 208 can be referenced for optimal understanding, where similar numbers will correspond to similar parts that will not be described in detail again.

[0088] The exhaust module 1100 may include an ultraviolet C (UV-C) LED 1102 mounted therein (such as at a location mounted to inlet port 808, exhaust housing 801, or along flow path 806 between inlet port 808 and filter 800). When the exhaust module 1100 is in a stacked configuration (similar to...), Figure 6 When arranged as shown, the UV-C LED 1102 can be powered (energized) along the power interface 608. The UV-C LED can be energized to kill and / or inhibit the growth of bacteria and other harmful organisms on the filter 800 and / or surfaces within the extraction module 1100.

[0089] The exhaust module 1100 may also include one or more UV-transparent windows (not shown), through which the UV-C LED 1102 can be illuminated with UV light. The exhaust module 1100 may also include light pipes, optical fibers, mirrors or lenses or combinations thereof (not shown) inside the exhaust housing 801, which can be used to distribute light from the UV-C LED to various surfaces or components inside the exhaust housing 801 as needed, thereby killing and / or inhibiting the growth of bacteria and other harmful organisms inside the exhaust housing 801.

[0090] Smoke extraction using photoelectric sensors Figure 12 Examples of at least one aspect of this disclosure are illustrated. Figure 8 A detailed view of the inlet port 808 of the extraction module 208. The inlet port 808 may include a light transmitter 1200 mounted (coupled) to a first side 1201 of the inlet port 808 and a second side 1203 (i.e., angled opposite side) mounted (coupled) to the inlet port 808 and positioned facing the light transmitter 1200.

[0091] The optical transmitter 1200 and the optical receiver 1202 can be connected via power interface 608 ( Figure 6 ) is powered and can be supplied via, for example, along the data interface 610 ( Figure 6 Wired or wireless connection with the head module ( Figure 6 ) controller 620 ( Figure 6 The controller 620 can power the light emitter 1200, causing light to shine (emit) from it toward the light receiver 1202. The controller 620 can determine the amount of smoke entering the extraction module 208 based on the amount of light received by the light receiver 1202 from the light emitter 1200, and control the modular surgical system 600 based on this determination. Figure 6 The various aspects of ) are described in more detail below.

[0092] Figure 13 It is a control based on at least one aspect of this disclosure Figure 6 A schematic flowchart illustrating example method 1300 of a modular surgical system 600. Method 1300 can be embodied in a controller 620 ( Figure 6 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input provided to controller 620 (such as on touchscreen 630) Figure 6 (to be executed at) (place).

[0093] refer to Figure 6 , Figure 8 , Figure 12 and Figure 13 Method 1300 may include receiving an input indicating the amount of light received at the optical receiver, as at step 1302. For example, controller 620 may power optical emitter 1200 so that light shines (emits) from optical emitter 1200 toward optical receiver 1202. Optical receiver 1202 may receive at least a portion (a certain amount) of the emitted light from optical emitter 1200, and controller 620 may receive an input from optical receiver 1202 indicating the amount of light received at optical receiver 1202.

[0094] Method 1300 may further include comparing the light intensity with a light threshold, as at step 1304. The controller 620 may compare the light intensity with the light threshold, which may be stored in memory 624 and may be retrieved by the controller 620. In some embodiments, the light emitter 1200 may be operable to generate a source light intensity measured in, for example, candela, lumens, foot-candles, or lux, and the threshold may be a percentage (fraction) of that source light intensity. The light threshold may be, for example, 99%, 90%, 80%, 75%, 60%, or 50% of the source light intensity, or any suitable percentage.

[0095] Method 1300 may also include relinquishing power to the pumping motor, as at step 1306. For example, based on the light intensity being greater than a light threshold, controller 620 may relinquish power to pumping motor 820 and loop back to step 1302, as described above.

[0096] Method 1300 may further include determining the motor speed of the exhaust motor based on the amount of light, as at step 1308. For example, controller 620 may determine the motor speed of exhaust motor 820 based on the amount of light being less than a light threshold. The memory 624 of controller 620 may include a lookup table that associates the amount of light received by light receiver 1202 with the motor speed of exhaust motor 820. In the lookup table, it may be specified that as the amount of light received at light receiver 1202 decreases, the motor speed of exhaust motor 820 should increase accordingly. For example, a first amount of light may be associated with a first motor speed, and a second amount of light less than the first amount of light may be associated with a second motor speed greater than the first motor speed. Therefore, as the amount of light received at light receiver 1202 decreases, potentially indicating an increase in smoke between light emitter 1200 and light receiver 1202, the motor speed of exhaust motor 820 will increase accordingly. Controller 620 may retrieve the motor speed of exhaust motor 820 from the lookup table based on the amount of light received by light receiver 1202.

[0097] Method 1300 may further include setting the pumping motor to a motor speed, as at step 1310, and powering the pumping motor at the motor speed, as at step 1312. For example, controller 620 may set the pumping motor 820 to operate at the determined motor speed. Controller 620 can then power the pumping motor 820 via power interface 608 (… Figure 6 The pumping motor 820 is powered at the determined motor speed.

[0098] Method 1300 may optionally include determining the amount of compensating blow-in to be provided, as at step 1314. Controller 620 may determine the amount of compensating blow-in to be provided to account for the amount of pressure lost due to exhaust, as described above. Controller 620 may determine the amount of compensating blow-in to be provided based on the flow rate of the smoke 812 entering inlet port 808 and the amount of time elapsed since the exhaust motor 820 has been powered; the flow rate may be measured by flow sensor 820a in, for example, cm... 3 The measurement is in units of / second, and the elapsed time can be measured, for example, in seconds, by timer 626. The compensation blow-in volume to be provided can be the blow-in gas 716 ( Figure 7 The volume of ), which can be expressed, for example, in cm. 3 Measured in units.

[0099] Method 1300 may also optionally include powering the blow-in motor to provide a compensated blow-in volume, as at step 1314. For example, controller 620 may be blow-in motor 702 ( Figure 7 ) to supply power to blow in gas 716 ( Figure 7 The blow-in module 210 drives the airflow to a patient, such as from which smoke 812 is drawn, to adjust the pressure within the patient's body. The controller 620 can keep the blow-in motor 702 powered until a compensating blow-in volume is provided. Based on the provision of the compensating blow-in volume, the controller 620 can de-energize the blow-in motor 702. In some embodiments, the controller 620 can provide a compensating blow-in volume after the exhaust motor 820 has been de-energized and has stopped drawing smoke 812 from the patient. In other embodiments, the controller 620 can provide a compensating blow-in volume to maintain pressure balance within the patient's body while the exhaust motor 820 is drawing smoke 812.

[0100] Automatic smoke extraction - Visual contrast Figure 14 This is a block diagram of another example of a modular surgical system 1400 according to at least one aspect of this disclosure. The modular surgical system 1400 may be similar in some respects to... Figure 6 The modular surgical system 600 is therefore best understood with reference to it. As illustrated, for example, the modular surgical system 1400 may include a head module 202 having a controller 620, a display screen 206 coupled to the head module 202, an inhalation module 210 stacked below and coupled to the head module 202, a visualization module 212 stacked below and coupled to the inhalation module 210, and a suction module 208 stacked below and coupled to the visualization module 212. For example, the modular surgical system 1400 may include additional modules, such as an energy module 204, as described elsewhere herein.

[0101] The modular surgical system 1400 may also include an insufflation cannula 1402 inserted into a patient's body cavity 1410, the insufflation cannula being in fluid communication with an insufflation module 210 to receive insufflated gas 716 therefrom. Figure 7 The modular surgical system 1400 may also include a drainage cannula 1404 inserted into a patient's body cavity 1410, the drainage cannula being in fluid communication with a drainage module 208 to aspirate (drain) smoke 812 from the patient's body cavity 1410. Figure 8 The modular surgical system 1400 may also include a visualization cannula 1406 inserted into a patient's body cavity 1410, the size of which can be set to receive an endoscope (camera) 1408 passing through it for visualization of surgical sites within the patient's body cavity 1410.

[0102] Although the modular surgical system 1400 is depicted as having three separate cannulas 1402, 1404, 1406, other embodiments are contemplated in which the visualization cannulas 1406 is omitted and the endoscope 1408 is introduced into the patient's body cavity 1410 via, for example, the insufflation cannulas 1402, and insufflation gas 716 is provided to the patient's body cavity 1410 via, for example, an auxiliary connector (such as a Luer lock connector) in the insufflation cannulas 1402.

[0103] During operation, endoscope 1408 can be manipulated to capture surgical images, such as live feeds, of surgical sites within the patient's body cavity 1410. Imaging data can be transmitted from endoscope 1408 to visualization module 212, such as via fiber optic cable 1409 or wirelessly. The imaging data can then be transmitted via data interface 610 (… Figure 6 The received imaging data is transmitted to the controller 620 of the head module 202. Based on the received imaging data, the controller 620 can display the image on the LCD 640 of the display 206. Figure 6 The surgical image 1420 is displayed on the screen, allowing operating room (OR) staff to view the surgical site in the patient's body cavity 1410 in real time.

[0104] During surgery, surgical instruments (such as...) Figure 3 A surgical instrument (one of surgical instruments 300, 330, 360) can be inserted into a patient's body cavity 1410 via a cannula (such as one of cannulas 1402, 1404, 1406) to perform surgery on tissue (such as at a surgical site visualized by an endoscope 1408). Performing surgery on tissue can result in smoke 812 ( Figure 8 The smoke is generated, thereby obstructing the field of view (FOV) of the endoscope 1408. A system and method are needed for automatically controlling the extraction module 208 to extract smoke from the FOV of the endoscope 1408.

[0105] Figure 15 It is a control based on at least one aspect of this disclosure Figure 14 A schematic flowchart of an example method 1500 for a modular surgical system 1400. Method 1500 can be embodied in a controller 620 ( Figure 14 ) memory 624 ( Figure 6 The algorithm in ) and can be controlled by the processor 622 of the controller 620 ( Figure 6 Based on user input to controller 620 (such as on display 206) Figure 14 ) touchscreen 630 ( Figure 6 (to be executed at) (place).

[0106] refer to Figure 6 , Figure 14 and Figure 15 Method 1500 may include receiving imaging data including surgical images, as at step 1502. For example, controller 620 may receive imaging data including surgical images from endoscope 1408, as described above. For example, the surgical images may be images of surgical sites within a patient's body cavity 1410.

[0107] Method 1500 may also optionally include displaying surgical images on a display, as at step 1504. For example, as described above herein, controller 620 may be located on LCD 640 of display 206. Figure 6 The surgical image 1420 is displayed on the screen, allowing operating room (OR) staff to view the surgical site in the patient's body cavity 1410 in real time.

[0108] Method 1500 may further include subdividing the surgical image into sub-parts, as at step 1506. For example, controller 620 may divide the surgical image into multiple sub-parts 1422, such as... Figure 14 The 4×4 grid shown. The number of sub-parts into which the surgical image 1420 is divided can be stored in memory 624. Although a 4×4 grid is shown and described, by way of example, any suitable number and size of sub-parts, such as a 6×6 grid, a 10×10 grid, or a 25×25 grid, can be used.

[0109] Method 1500 may further include detecting contrast changes in at least one of the sub-parts, as at step 1508. For example, controller 620 may utilize Fast Fourier Transform (FFT) to evaluate the contrast of each sub-part 1422 and use it to detect contrast changes in sub-part 1422.

[0110] Method 1500 may further include determining whether a change in contrast has already occurred in all sub-parts, as at step 1510. For example, based on the detection of a change in at least one sub-part 1422 of the surgical image 1420, controller 620 may proceed to evaluate each sub-part of sub-part 1422 to determine, for example, via FFT, whether each sub-part of sub-part 1422 has already had a change in contrast.

[0111] Method 1500 may also include generating an alarm indicating that the source of the imaging data needs to be adjusted, as at step 1512. For example, based on the controller 620 determining that the contrast of all sub-segments 1422 has changed, the controller 620 can conclude that image 1420 is out of focus, which may have caused a contrast change in each sub-segment of sub-segment 1422. Therefore, the controller 620 can generate an alarm, such as via speaker 650 ( Figure 6 ) auditory alarm or via LCD ( Figure 6 The visual alarm of the endoscope 1408 notifies the OR staff that it should be adjusted, such as refocusing.

[0112] Method 1500 may also include powering the exhaust motor, as at step 1514. For example, based on controller 620 determining that only a portion (less than all) of the contrast of sub-segment 1422 has changed, controller 620 can conclude that smoke 812 ( Figure 8 The FOV is obstructed because it exists within the patient's body cavity 1410. Therefore, the controller 620 can power the suction motor 820 ( Figure 8 The device is powered to aspirate (extract) smoke from the patient's body cavity 1410 via the extraction cannula 1404. The controller 620 can set the speed of the extraction motor 820 according to the techniques described elsewhere in this document.

[0113] Therefore, controller 620 can monitor surgical images captured by a camera (e.g., endoscope 1408) and determine whether changes in the images are due to camera defocusing or the presence of smoke. Based on this determination, controller 620 can select appropriate actions, such as instructing OR staff to defocus the camera or powering the suction motor.
